APPLIANCE FOR FIXING AND CUTTING OFF THE UPPER OR WEARING PORTIONS OF COIVIPOUND TRAMWAY-RAILS.

T 0 all whom "it m my concern:

it known that .l, EDGAR .ltnonas, a subject of the King of Great Britain, residing at Scholes, near Leeds, in the county ()1 York, England, have invented certain new and useful improvements in appliances for lixing and cutting oil the upper or wearing port ions of compound trannvay-rails, 01 which the following is a specilication.

This invention has rel'erenee to the appliance for lixing the upper or wearing portions of compound tramway rails on to their base or girder portions described and shown in the specification oi United States Patent No. 717,224, dated Dec. 31), 1S0), and also to the appliance for cutting 011' the upper or wearing portions of compound tramway rails described and shown in the specitication of United States Patent No. 718,362, dated Jan. 13, 1903; the leading'ebject ol the present invention being to combine the two arrangements in one machine, or, in other words, to so arrange the machine hitherto employed for fixing or rolling on the upper portions of compound trannvay rails that the same machine may be readily transl'ormed and employed for cutting oil the upper portions of compound tramway rails, and vice versa.

Another object 01 the invention is to eliect the cutting-cit operation in a new and better way by means of a cutter which is caused to rotate with its shalt by frictional contact, whereby the cutting oi a key way in the small cutter is avoided, and the danger oi" fracturing said cutter by torsional driving strain is obviated.

The invention consists in. certain novel combinations of parts lmreinaltcr described and claimed.

A sheet 01" drawings accompanies specification as part thereof.

Figure 1 represents a front elevation of the appliance adjusted for the cutting oil operation; Fig. 2 is a like view of the removable parts of the cutting-oil mechanism detached Fig. 3 represents the cutter shait on a larger scale, with its gear, the cutter and the cutter clamp in section; and Fig. i is an end view projected from Fig. 3.

Like reference characters refer to like parts in all the figures.

The appliance when adjusted for the roll ing-on 0r fixing operation, may, for the this Specification of Letters Patent.

" s of this invention be ol' the construc ol 717,224: that is to say, it may have a su1t part able carrying irame, 1, provided with a rotler, a, adapted to run in contact with the the top portion 01' the rail it; a pair o1 arms, 2 and 3%, pivoted in said l'rame t heir upper ends on studs, 1) and 0, parallel with the rail, and provided with bearings, 41 and 5, (or a pair ol' downwardly converging shalts, similar to those shown at 6 and T; power-driven gearing including a horizontal worm-(anrrying shaft, (Z, and worm and spur gearing transmitting rotation therefrom and terminating in spur gears, S and 9, which are remowibly keyed and clamped upon the upper ends of said shal'ts at 6 and 7, respectively, the lower ends of the shafts carrying the lixing rollers; a hand wheel, 6, and mechanism actuated thereby terminating in a pair of toggle links, 10 and 11, pivoted at their outer ends to the respective arms 2 and 3; and, linally, suitable means including a lace plate,f, Fig. 1, lo! supporting the frame 1, and the parts carried thereby, in juxtaposition to the driving shaft d, which is part oi a motor or engine n'iountcd on a traveling bogie.

In order to adapt the machine for cutting oil as well as for rolling on, it is provided with a second pair o'l shal'ts, (i and 7, adapted to be substituted for-said shafts of the fixing rollers and to be driven bythe same gearing. The gears 8 and 9 may for this purpose be removably attached in any approved way, as, for example, by screw-nuts 12 and keys 13, Fig. 3.

The shafts (3 and 7 carry at their lowerends respectively a downwardly tapered supporting and propelling roller, 14:, having a suitably roughened periphery to contact with one oi the llat sides of the cap or top portion of the rail it, and a steel disk cutter, 15, hav ing a sharp (\I-shaped) peripheral edge opposed to the depending 'Ilange at the opposite side of the top portion of the rail, said cutter being of substantially the same diameter as said roller so as to be driven in common therewith by spur gears of one and the same size. In this way, the appliance hitherto employed for rolling on is rendered equally a )plicable for cutting oil; the transforming oi the machine, by simply removing the two shafts carrying the fixing rollers employed for rolling on, and inserting the two shafts 6 and 7 carrying the supporting roller 14 and the disk cutter 15 employed for cutting off, and vice versa, being easily and quickly performed.

The roller 14 may be integral with the lower end of its shaft 6 or fixedly attached in any approved way.

As shown in Figs. 3 and 4, the steel disk cutter 15 is preferably clamped against the lower side of a collar, 16, fast on its shaft, 7; the lower protruding end of this shaft being reduced and screw-threaded, and provided with a key, 17, a loose collar, 18, having a key way, 19, engaging said key 17, and a clamping-nut, 20, contacting with said loose collar 18. In this way the cutter 15 is caused to rotate with its shaft 7 by frictional contact; the cutting of a key way in the small cutter 15 is avoided, and thus the danger of fracturing said cutter or rendering the same liable to fracture under torsional driving strain is obviated.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a fixing and cutting off appliance for the purpose specified, the combination with a pair of driving gears of a pair of downwardly converging rotary shafts attached respectively thereto and respectively provided at their lower ends with a downwardly tapered supporting and propelling roller having a roughened periphery adapted to contact with one of the flat sides of the top portion of a compound tramway rail, and a disk cutter of substantially the same diameter as said roller, having a peripheral cutting edge to contact with the depending flange of such top portion at the opposite side of the rail, substantially ashereinbefore described.

2. In a fixing and cutting-off appliance for the purpose specified, the combination of a pair of pivoted arms having bearings for a with the depending flange of said top portion at the opposite side of the rail, and means whereby said cutter is caused to rotate with its said shaft by frictional contact, substantially as herein'before described.

3. In a cutting-off appliance for the purpose specified, the combination of a pair of pivoted arms having bearings for a pair of rotatable shafts, means for driving such shafts, means for pressing their lower ends toward each other, a pair of downwardly convergii'ig shafts mounted in said bearings one of them furnished with a supporting and proadapted to contact with one side of the top portion of a compound tramway rail and the other shaft constructed with a fast collar and a reduced screw-threaded protruding portion at its lower end, a disk cutter of substantially the same diameter as said roller, contacting frictionally with the lower side of said fast collar, a loose collar keyed to the shaft and contacting frictionally with the lower side of the cutter, and a clamping nut contacting 1 with the lower side of the loose collar, substantially as hereinbefore described.

In witness whereof I have hereunto set my I hand in thepresence of two witnesses.

EDGAR RHODES.
